CVE-2018-18628: Deserialization of Untrusted Data

October 24, 2018 (updated September 2, 2021)

An issue was discovered in Pippo 1.11.0. The function SerializationSessionDataTranscoder.decode() calls ObjectInputStream.readObject() to deserialize a SessionData object without checking the object types. An attacker can create a malicious object, base64 encode it, and place it in the PIPPO_SESSION field of a cookie. Sending this cookie may lead to remote code execution.
